mb/siemens/mc_ehl7: Enable reboot after HW Watchdog expiry

Browse source 
Configure the board to perform a hardware reboot when the TCO watchdog
expires. This is achieved by using the default Kconfig option
SOC_INTEL_ELKHARTLAKE_TCO_NO_REBOOT_EN with 'n'.

TEST=Verified in the OS on mc_ehl7:
Checked IO-mapped register 0x408 Bit 0.
Without this patch, the bit is 1 (No Reboot enabled).
With this patch, the bit is 0 (Reboot on expiry enabled).
